Same problem here. Feisty 32bit. Using Network manager. AMD Turion x2 laptop. Atheros wireless.

The problem manifests itself for me as incredible desktop slowness when connected to some wireless networks. Top shows no excessive CPU use or any problem processes. Nothing interesting in the system log.

When I launch programs, they simply don't show up -- the panel shows "Starting xxxxx", and the application may load up after 30 seconds or so, or even longer (sometimes not showing up at all). Right-clicking network manager in Notification Area, and selecting "Disable Wireless", or changing to a different wireless Access Point, causes the applications I am waiting for to suddenly appear!

"slowness" is a misnomer here -- "uselessness" is more like it. Everything -- even gnome-terminal is affected. Firefox seems to have connectivity -- but waiting for 30 seconds just for URLs to resolve makes it pointless.

Interestingly, if I right-click and choose "Disable networking", without selecting "disable wireless", the slowness usually does not stop.

It seems to be somewhat random -- it affects about 70% of APs I try to connect to. (Invariably, only affecting the ones I *want* to connect to). These are all unsecured, public access points.

Network Manager is managing all my connections -- the only change over default I have made is adding some DNS server to the prepend list in /etc/dhcp3/dhclient.conf, as my router's DHCP/my ISP at home is flaky, and I get DNS timeouts unless I statically configure DNS servers. (problem has existed for years).

I notice that in my case, the loopback interface also didn't have a hostname assigned in /etc/hosts. Will try adding and will report back as to whether this fixes the problem.

*PLEASE* decide on an importance for this bug. Nothing more irritating/embarrassing than taking your laptop to a coffee shop and spending the entire time trying to figure out why everything is slow as molasses.
